Victor Jr Head Build Up - looking for thoughts from experienced folks
Bought a new pair of 77179 Victor Jrs - from PSP last week- with valves, no hardware. 60 cc chamber,210 cc Intake ports; 75cc exhaust. 2.05"/1.60" SS valves installed and seated.
Motor is 333 cid stock block, internally balanced, Eagle forged crank JE pistons, ARP studded, 2 girdles, ATI alum damper, Crane big $ hydr roller lifters, Kooks 1-7/8 ceramic headers.
Comp Cam is mech/hydr 236*/248* @ .050" .589" lift with 1.72 Ford alu roller rockers.
Will be flowed on PSP's bench, then cleaned up an ported, flowed again and cc'd.
Deciding if its worth measuring all 16 ports before and after. Also will be getting the matching Victor Jr carb manifold opened up more and also port matched. Fuel distribution is not nice on #1 and #8, despite already having been cleaned up. Pro Systems 780 road race carb will go back to Patrick for rebuild/new fuel curve once head flow is finalized.
Heads will be ARP stud mounted; 11:1 comp ratio, some kind of conventional gasket; unless Paul says wire loc; which I doubt.
Hardware: 10* titanium locks and retainers, beehive springs
Rockers will be either existing Ford Racing 1.72 with a stud girdle and guide plates on 7/16" studs; r will go to T&D shaft rockers - 1.75/1.75.....money allowing.
Thoughts and advice from those with Victor Jr and high end head / valvetrain experience only pls.
Motor is for road course and street with 4.10 gear, max power 6500 rpm or less, I hope. Pulls to 7000 now, with iron Dart heads, max hp was at 6000 with 1-5/8" Mac headers previously.
Expected to make app 40 hp more than now (currently app 400 rwhp) carbed, naturally aspirated; plus lose 40 lbs in weight. Thx for reading. Will post pics - this will become a mini build.
